Sounds from Scientific, Meteorological and Commercial Satellites 2014-2016

This part of my audio collection is dedicated to commercial and scientific satellites. I started this separate section when Greg Roberts, ZS1BI in Cape Town, started to convert some of his old recordings from a tape recorder with elastic belt drives to electronic format. Greg is a retired professional astronomer and since 1957 has been actively involved in the tracking of artificial satellites, both by optical and radio means. Click on his picture to the right to get more information about him and his activities.

#39640
(2014-015A)

DMSP-F19, also known as DMSP 5D-3 F19 or USA 249, is a US Department of Defense weather satellite launched on an Atlas 5 rocket from Vandenberg into a 850km high sun-synchronous orbit. DMSP is a space- and ground-based system used to collect and disseminate timely global environmental data to the Department of Defense and other governmental agencies. This environmental data consists of visible and infrared cloud cover and other specialized meteorological, oceanographic, and solar-geophysical information required to support the war fighter. DMSP satellites “see” environmental features such as clouds, bodies of water, snow, fire, and pollution in the visual and infrared spectra. The data can be used to determine cloud type and height, land and surface water temperatures, water currents, ocean surface features, ice, and snow. DMSP data are processed on the ground, interpreted by meteorologists, and ultimately used in planning and conducting U.S. military operations worldwide.

It is part of the second LONESTAR (Low Earth Orbiting Navigation Experiment for Spacecraft Testing Autonomous Rendezvous and Docking) mission. The other satellite is BEVO-2 which will be released by Aggiesat-4 later. AggieSat4 was developed and built by Texas A&M University and measures 75x75x35cm. It is three-axis-stabilized. AggieSat4 features two low-data-rate (LDR) radios, a high-data-rate (HDR) radio, a crosslink radio for short range communication with the BEVO-2 satellite and a DRAGON GPS payload. Its main objectives are: demonstration of 3-axis-stabilization, collection of GPS data, recording video of the deployment of the BEVO-2 satellite using its 2MP camera, rendezvous investigations with BEVO-2.

AggieSat-4 features a telemetry beacon downlink on 436.250 MHz in 9k6bd FSK or 153k6 FSK. The beacon transmits once every 60 sec using the callsign WH2XGN.

BEVO-2
#413xx
(1998-067Hxx)

BEVO-2 was built by students at the University of Texas. I was released inside of AggieSat-4 from the International Station on January 29th 2016 and was planned to be released by Aggiesat-4 using an ISPOD deployment system at a later point in time. BEVO-2 uses the 3U Cubesat form factor and measures 10x10x34cm. BEVO-2 features a UHF/VHF terminal for data downlink to and command uplink from ground. In addition it features qa crosslink radio unit for communication with AggieSat-4. With its cold gas thrusters it will perfrom maneuver exercises with AggieSat-4.

BEVO-2 features a telemetry beacon downlink on 437.325 MHz in 38k4 FSK and CW.

BEVO-2 was prematurely deployed from AggieSat-4 and never activated.

KMS-4
Kwangmyongsong 4
#41332
(2016-009A)

Kwangmyongsong 4 is a North Korean earth observation satellite built by the National Aerospace Development Administration (NADA). Reportedly the satellite carries some earth observation equipment. Initial unconfirmed images of KMS-4 show a cubic body with two deployable solar arrays and two camera apertures on the nadir side.

Kwangmyongsong 4 launched on February 7th 2016 on an Unha-3 rocket from the Sohae Satellite Center in Ch’olsan County, North P’yongan Province. It entered a sun-synchronous orbit of 465 km × 501 km with an inclination of 97.5°. No signals have been detected from the satellites and ground observations showed, that it was initially tumbling. An analysis by Bob Christy suggests a significant shortfall in 3rd stage performance of the Unha-3 launch vehicle.
